Two reusable D3 legends demonstrate how to encode data through color and size. The color legend uses `d3.scaleOrdinal` to map fruit names to categorical colors, while the size legend uses `d3.scaleSqrt` to map numeric values to circle radii. Both legends are implemented as custom D3 functions that append SVG circles and text elements, using `.merge()` for efficient updates and `.exit().remove()` for cleanup. The rendering is entirely SVG-based within a single `<svg>` element, styled with CSS classes.

Color and Size Legends

Two customizable legends demonstrate how D3 v5 encodes data through color and size. The color legend uses `scaleOrdinal` to map fruit categories to distinct hues, while the size legend employs `scaleSqrt` to represent numerical values through circle radii. Both legends are constructed through reusable functions that bind data to SVG groups, with legends rendered as circles and text labels. The color legend applies `attr("fill", colorScale)`, while the size legend filters zero values from its ticks and spaces circles vertically.

Color and Size Legends

Two reusable D3 legends demonstrate how to encode data through color and size. A color legend maps ordinal fruit names to distinct hues using `scaleOrdinal`, while a size legend translates a quantitative scale from 0 to 10 into circle radii via `scaleSqrt`. Both legends render as SVG groups with labeled ticks, using `selection.merge` to update existing elements efficiently. The examples show legend construction with configurable spacing, text offsets, and tick counts for flexible chart annotations.

Color and size legends

Two adjacent legends illustrate how to construct reusable D3 legend components. A color legend uses `d3.scaleOrdinal` with fruit types mapped to red, yellow, orange, and green, rendering circles with corresponding fills and text labels. A size legend uses `d3.scaleSqrt` to map values 0–10 to circle radii, with ticks generated via `sizeScale.ticks` and positioned by cumulative spacing. Both legends are appended as SVG groups, with enter/merge/exit selections managing dynamic updates.

Color and Size Legends

Two reusable legend components demonstrate color and size encoding in D3 v5. The color legend uses `scaleOrdinal` to map fruit categories to distinct colors with fixed-radius circles, while the size legend uses `scaleSqrt` to map numeric values to circle radii. Both legends render as SVG groups with tick marks, using D3’s data join pattern and `.call()` to apply each component. The size legend filters out zero values and reverses tick order, with text offset dynamically calculated from each circle’s radius.

Color and Size Legends

This example demonstrates how legends can visualize both ordinal color scales and quantitative size scales. A color legend maps fruit names to distinct hues using `d3.scaleOrdinal`, while a size legend translates a numeric range into varying circle diameters via `d3.scaleSqrt`. Both legends are constructed as reusable functions that append SVG `<g>` groups and circles, using D3’s selection and merge patterns to handle updates. Text labels accompany each circle, positioned relative to the circle’s radius.

Color and Size Legends

This example demonstrates how to create custom color and size legends for D3 visualizations. The color legend displays four categorical fruits using a d3.scaleOrdinal with distinct color ranges, while the size legend uses d3.scaleSqrt to map numeric values from 0 to 10 to circle radii. Both legends are built using reusable functions with enter/merge/exit patterns, rendering SVG groups with circles and text labels. The code uses D3 v5 selection methods and scales to position legend items with configurable spacing and text offsets.

Color and size legends

This example demonstrates the use of two separate legends to map data values to visual encodings. A color legend shows categorical fruit names with a d3.scaleOrdinal scale, while a size legend represents numbers from 0 to 10 with a d3.scaleSqrt scale that maps values to circle radii. The legends are rendered as SVG groups using custom reusable functions, with circles and text labels arranged vertically. The underlying data scales and spacing are defined in the JavaScript code, with fruit categories and numeric ranges specified directly.
